It worked. She felt the tube of it expanding, displacing other organs of her body, lengthening and thickening. It swelled up into her abdomen, into her midriff, and pushed up between her lungs, past her heart, and on to the base of her throat. She felt queasy as her body adjusted, making way, but things continued to function. As the demoness had explained, shape changing was topological; aspects could be stretched or compressed without changing the essential nature of the body. Of course it could be a challenge to assume the eight legged form of a giant spider; that required greatly extending some toes to resemble legs, and not all the eyes were operative. But a change from the likeness of one human being to another was elementary. This was in between: an adjustment of the size of one portion, and shifting of position of others. The demon waited patiently, his member never slackening. Finally she had it. She glanced at the full length mirror, and saw that her outline was unchanged; she retained her hourglass configuration. It was only the inside that had changed, and that at this point was a mere flattened tube.
“I believe I’m ready, to whatever extent is possible,” she said. “At any rate, it will have to do. Now you can have sex with me.”
The demon stepped forward, put his hands on her hips, lifted her up into the air, drew her in, and set her crotch on his member. She felt the hot tip of it nudging her cleft, and hoped she had made herself big enough. He let her weight drop, slowly, and that carried it down on the huge hot pole. She thought of the impalement stake the First Branch had set her on. But now she was ready for it, she hoped, and this one was rounded, not pointed.
She felt the phallus pushing in. Her flesh stretched around it, like an elastic condom, giving it room without any to spare. The great dome of it distended the aperture, denting it inward. Could she stretch enough? It seemed to be sticking.
Then there was a jet of warm taffy, or maybe petroleum jelly, and her hole became slick with lubricant. The phallus slid in, like a piston, following the greased channel, opening it up. She glanced down and saw that the member was half a foot deep, but at least three quarters of the shaft was still to come, as it were. She wriggled her torso, spreading the juice, and slid down farther, passing the halfway mark. Her belly was swelling with the size of it, sacrificing her wasp waist, but there was no pain; maybe the lubricant had an anesthetic property too.
The demon continued to lower her, and his member shoved on up in side her. She felt it passing her intestines, her kidneys, her liver, her heart, her lungs. Her breasts became more prominent, forced outward by the mass in her chest. Then, just as it reached the limit and threatened to block her throat, she felt the base of the phallus come up against her vulva. It was all in!
She sighed with relief, and felt her lungs shifting around the giant pole within her. She had accommodated the colossus. Two feet long, five or six inches thick, a genuine monster, encompassed. It was a singular victory.
But the climax was still to come. What horrific eruption was likely to come from such a gargantuan member? She rested in place, her legs dangling, feet not touching the floor, awaiting the culmination.
The phallus heated and swelled a bit more, readying its delivery. She felt a tremor down in the scrotum, maybe only a two on the rectum scale, but suggestive of the blast to come. It rumbled in the channel, and the organ became yet more turgid. At last the fluid surged out with such lava-like force that she was lifted a foot, sliding up the shaft. Then she settled again, pneumatically, as the flow diminished, and her weight pressed it out to drool onto the floor.
But that was only the half of it. The moment the turbulent elixir struck her inner flesh, the wondrous delight of it radiated outward through her body, transforming it into a vessel of transcendent joy. Her heart and lungs seemed to function more efficiently, her breasts fairly glowed with enhanced sex appeal, and her head became marvelously clear. As the substance coursed downward, her guts and kidneys shared the joy, and her vagina became a column of rapture.
“Oh, demon,” she gasped. “I never had an orgasm like that!” She lifted her face and managed to reach his face, kissing him on the tusked chin. “I didn’t have to fake anything.”
But all things had to end, and though the phallus remained rigid, the pleasure slowly faded as the ejaculation lost its freshness. The demon put his hands on her hips and lifted her off, inch by inch and foot by foot, until her crevice cleared the divine pediment.
She staggered to the bed and flopped onto it, driblets of the demon’s semen still leaking from her cleft. She lay there, recovering from an experience that had become far more rewarding than she had expected. She had taken in quadruple the ordinary length, and had quadruple the pleasure.
She slept, delightfully exhausted. At one point she woke, discovering Chance with her, nursing. The demon must have brought him, and made no further demand on her. It just might be that the experience had been as fulfilling for him as for her, and he needed no further contact.
In the morning she got up and washed, dressed, and ate while nursing Chance. This apartment, like the others, was well appointed; everything she needed was there.
She poked an exploratory finger into her vagina and found that it had reverted to its normal configuration. That was just as well; she didn’t need a two foot long vagina when not having sex. However, she suspected that she would be able to lengthen it again more rapidly at need; she had established the template.
The demon reappeared. Oops, she might have reverted too soon. She put Chance down and indicated her body. “Do you wish another session?”
He shook his head no. It seemed that once was enough, and he was just checking in on her.
“I’m fine,” she said, realizing that he was the strong silent type, having no actual mouth orifice. “You are a good host.”
He nodded, and turned away. But she found she couldn’t leave it at that. She went after him and stood before him. “Lift me up so I can reach your face.”
He did so, and she kissed him on the mouth region, between the tusks. “You were great last night, Branch Five. We really must do it again some time.” She had found that it paid to flatter the demons, but what she said was true. It had been a truly transcendent experience.
He set her down and departed. She had the rest of the morning to her self.
At noon Prior arrived, ready for the final challenge. Tantamount related to him, of course; he was indeed the right man for her, apart from being the father of her child. This whole business of the tower and demon combats had satisfied her. In time she would surely come to love him. But she was sorry that the demons had to be dispatched. They were not evil, merely trying to do their job, which was to recover and guard the Spire. Even the mean-spirited First Branch had that useful magic carpet form, and he hadn’t abused her once she accepted his persistent phallus. In fact it had been an interesting way to travel; his penis, like the others, had radiated a certain pleasure into her body.
She was allowed to bring Chance out and witness the event. Apparently once she had committed to indulging him, the demon trusted her and gave her full freedom. That suggested an underlying decency she appreciated.
Prior and the demon entered the pentacle. They grappled. The demon lifted the man up and shoved his face at the end of the perpetually erect phallus. That would be where he farted from, of course; the demon had no other orifice. She saw that Prior couldn’t get his posterior into place; his whole body was in the air.
The demon’s fundament quivered as he readied his emission. Tantamount held her breath. Prior needed to break this hold in a hurry or he would be farted into oblivion.
